This intrigued me. I decided to see what would happen if you plug a Windows Phone 7.5 device - my HTC HD7 in this case - into a Windows 8 machine (the release preview). The answer? Nothing happens. If you combine Microsoft's prime desktop operating system and prime mobile offering, nothing happens. No dialogs, no sync options, no check for updates, no backups, no audio/video transfer, not even a mount or a dialog to download Zune. They've got only a few months to address this.
